FIREARM.

Application led January 20, 1927-. Serial No. 162,317.

- My invention relates to firefarms, of theV Fig. 2 is a broken longitudinal section of theifire-arm with thestock broken away and theempty shell of the cartridge being ejected.

Figs. 3, 4 and 5 are slightly enlarged cross sectional views taken on lines 3 3, H and 5 5, respectively, of Fig. 1.

Fig. 6 is a cross section on line 6-6 of Fig. 2.

Fig. 7 is a fragmentary plan View showing a` portion of the gun barrel. and a slidable sleeve mounted thereon.

i Fig. 8 is a fragmentary plan view of a portion of the frame, the trigger, and a safety catch.

Fig. 9 is a fragmentary view partly in section of a modified form of stock and trigger mechanism.

' Referring in Ydetail to the different parts, '2 designates the tubular frame of the firearm, 4 the barrel, and 6 the stock, which latter is preferably in -the form ofa cane handle and` has a forwardly projecting reduced terminal 8 removably securedwithin the .rear end of the frame` 2- by suitable means such as a screw 10.

'Bhe barrel 4 has' a chambered breechl12 for-thereception ofavcartridge suchA as desgnated bythe characterv A, which; may be loaded with eitheraa bullet or shot as-k pre- 'r i ferred. The barrel 4 has an integral rearwardly extending tubularr extensionA 14 in which the reduced forward end of the frame Y 2;is secured by suitable means such as screws slot 18 and"V reliably holding .the cartridge withinthe breech 12. The breech block 20 is hinged or pivotally connected at its forward end to the breech 12 as indicated at 22, so that it may drop to uncover the slot 18, but is normally held in closed position by a sleeve-24 which is slidably mounted upon the framev 2 and the extension 14 andwhich is capable of performing other functions hereinafter referred to in addition to holding thebreech block 2() in closed position.

The; breech block 20has a longitudinal bore 2 6 which is in axial alinement with the'A bore ofthe barrel 4 when the breech block 20is in closed position as shown by Fig. 1.

The. bore 26 is provided with a firing pin 28 which is operably held inplace by suitable means such as a screw 30 threaded into the side of the breech blockl 2O and projecting between two circumferential shoulders 32 and 33 upon the firing pin 28 for limiting the movement of the latter. A` coil spring 34 pressing against the shoulder 32 and a shoulder 36 near the forward portion of the bore 26 normally holds the firing pin 28 in its backward or safety position, Fig. 1, so that its reduced forwardv endy 38 will be spaceda short distance from the rear end ofV the cartridge A.

40 designates a reciprocatory hammer which is wholly concealed within the frame 2 and arranged in axial alinement with the firing pin 28 when the breech block 20 is closed. The reduced rear portion of the hammer 40 is slidably mounted within atubular guide 42 securedl within the rear portion of the frame 2 by suitable means such as screws 44. The guide 42 has a longitudinal slot 46 coinciding with a similar slot 48 formed in the lower portion of the frame 2 to permitthevoperation of a pin 50 which is secured at its inner end to the hammer 40 l forthe purposeof cooking the latter and also for limiting its forward movement by' contacting the forward end of saidslot 46.

52 designates the main spring for propelling the hammer 40 forcibly against'the firing pin 28 after said `hammer 40 has been released by a vertically movable detent 54 having an opening 56 throughwhich the rear portion of the hammer 4() projects. The opening 56 has a straight bottom portion forming a shoulder 58 `for engagement with a shoulder 60 formed on the hammer- 40 by recessing itsunder portion, see Figs. 1 and 2.

A spring 64 normally holds the detent 54 in raised position for engagement with the Y Vshoulder 60.4 Said spring 64 bearsat oneV end against the under side of the'detentf54 and at its opposite end ina eupjjsliapedscrewy G6 threaded intothe lower portion, of the' frame 2.y `The detent 54 isguided in its;

' A vertical movements by a trigger' 68 and ga pin or screw 70, whichlatteris secured to 'the j lower/portion of the detent54andprojects axially through the springf64 andthe cupshaped screw The trigger 68, which is Ifpreterably in thefiormfof a pin, as shown'v by I*`ig. l', `extends through a complementaly opening in -thewfrainevZand is'seeured at its lower end 'tothedetent54 and'provided'at vr"catch74ttor*operating thefla'tter and 'a the 'empty' s opened. s'

Vshoulder, 86 is tormed'upon theitorward end j of said safety catch for engagementl with tlief' v"under side of the head 72 for holding the trigger 68 'in Safety position. j vQ84-designatesa combination injector and ejector which is slidably mounted ina longitudinalslot' 87 arranged in the barrel extension 14 at a' pointl immediately above' the breech vblockvv 20. Said injector f and ejector 84 has a notchv 88 at lits under side for receiv-l ingf'a portion of the flange' B of the cartridge A, so' thatwthev latter canbe readilyl inserted in the breech 12 4or ejee't'ed'there# from. 'A rod 90 is fixed at its torwardend f Ato the injector and ejector 84 and-extends Vrearwardly through aguide 92 in the ior-f ward portion of vvthe fraine'2. The rear end yof the yrod is providedwith a Vhead 94' l[against which lthe rear end of a coil 'spring 96 presses, the 'forward end of lsaid lspring bearing'against the guide 92 or`the purpose of retractin the injector and ejector 84 with ell 'when the vbreech block`2'0` isV j I l4u la breech blocklhinged. to-said'barrel'and `AIn ypractice the gun Vmay beloadedl by grasping the sleeve 24 and pushing the'samefl baelrwardly tov permit the breech block 20 f to swing to open position. The forward end" ofthe 'cartridge is then insertedjin thebreech 12 Whilezthe'lange'Bis'placed in the notch "88 `ofthe `injector and ejectorf84, which is then pushed forwardly untilV the cartridge vflange B c'ontacts the breech 12; Thebreech n block 2Q is then Aclosed 'and 'securedin Asuch `position with the sleeve 24-which isshoved forwardly against the breech 12'. YVhen' the"V sleeve24- ismoved rearwardly to allow the Vbreech block 20 to open as hereinbefor'e stated;y said sleeve 24 contacts the pin 50 and pushes' the latter rearwardly'with the'hammer40 until the'shoiilder 60 paeses slightly to the rear of the detentV 5 4, which latter is immediately pushed upwardly front VVof said` until the shoulder '86 engagesunder the head v'and pushes the safety catch T4 rearwardly/7 1?,
